int PQserverVersion(const PGconn *conn);
</synopsis>
Applications may use this to determine the version of the database server they
are connected to. The number is formed by converting the major, minor, and
revision numbers into two digit numbers and appending them together. For
example, version 7.4.2 will be returned as 70402, and version 8.1 will be
returned as 80100 (leading zeroes are not shown). Zero is returned if the
connection is bad.
